Q.  How can I convert a HashMap's values into a sorted ArrayList?

A.	ArrayList's constructor takes a HashSet so its pretty easy:

HashMap<String,Integer> h = someCodeToMakeTheHash();
ArrayList<Integer> vals = new ArrayList<Integer>(h.values());
Collections.sort(vals);

h.values() gives as HashSet.
